relative t6 the opening 2 and said pipe is retained in its adjusted position by the set screw 20 threaded through the collar 16. A conduit 21 extends through the pipe 17 and carries on its inner end a suitable fuel atomizer or burner 22 which normally projects a slight distance beyond the burner shield 18 and said conduit is connected at its opposite end to a suitable coupling 23 carrying a valve 2% which controls the flow of fuel from a suitable flexible feed pipe 25. The coupling 23 extends through a ball casting 26 mounted on the end of the pipe 17 by set screw 27, and said coupling is retained in position in said casting by the ads justing screw 28 which extends through said casting.- -A suitable sight opening 29 is formed in one of said gates and the same is normally covered by a pivotally mounted cover or disk.

It will be apparent bycxaminiiig Fig. 1 of the drawings, that when the gates 11 are swung inwardly, as in the dotted lines, air

will be admitted through the openings controlled thereby in the front wall of the air chamber and the gates will prevent the direct glare from the burner flame from being in a direct line with the air inlet openings controlled by the gates.

By my improved construction, I have provided a device which is capable of attachment to any well. known type of furnace without altering the same, and without the necessity of the furnace being formed with heating chambers orcompartments therein.

I have also provided a device which is adapted for positioning over the furnace door opening to provide the air chamber exterior of the furnace front wall, and one in which the burner and burner shield are capable of adjustment relative to the fur nace door opening to regulate the position of the burner and shield within the air chamber, and, have provided a swinging gate structure which is so constructed as to enable air to be admitted into the air chamher without forming an opening in direct alinement with the burner and the exterior of the air chamber through the door opening. By providing upper and lower swinging gates for admitting air into the air chamber, 1- am enabled to admit air both above and below the burner and am also enabled to control one air supply independently of the other.

Having thus descrlbed my invention what I claim as new and desire to ters Patent is 1- 1. In a device of the class descrilmd, a furnace formed with a door opening leading to the fire box, an air chamber sccurer to the furnace front wall and surrounding said door opening, a fuel burner extending protect by Letfront of said door opening, aburner shield surrounding said burner, means foradmitting air to said air chamber and comprising a movable gate supported by the walls of said chamber, said gate when in open position providing a passage for the admittance of air into said chamber, and adapted to intersect a direct line from said burner flame to the air inlet opening in said chainber.

2-. In a device of the class described, a furnace with a door opening leading to the fire box, an air chamber secured to the furnace front wall and surrounding saiddhor opening, a support carried by said air chamher, a burner extending into said air chamher and adjustablv mounted in said support, a burner shield surrounding said burner, a

flexible connection for feeding fuel to said burner, inwardly swinging gates hinged to said support for admitting air into said air chamber, and means for retaining said gates in their adjusted position. 7

3. In a device of the class described, a furnace formed with a door opening communicating with the fire box, an air chamber detachably secured to the furnace front wall and surrounding said door opening, a support extending across the front of said air chamber, upper and lower inwardly swinging gates hinged to the opposite side edges of said support, means carried by the gates for/retaining the same in their adjusted position, a tubular member extending through said support into said airchamber and adjustable therein, a burner shield carried by one end of said tubular member, a burner mounted in said tubular member adjacent said shield, and a flexible fuel supply pipe connected to said burner.

In 'a device of the class described, a furnace formed with a door opening communicating with the fire box, an air chamber (letachably secured to the furnace front wall and surrounding said door opening, a support extending across the front of said air chamber, upper and lower swinging gates hingei'l to the opposite side edges of said support, means carried by the gates for retaining the same in their adjusted position, and a burner adjustably mounted in said support and extending into said air chamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
